Tutors may apply to students who are a good fit, while tutors can gracefully decline tutor requests from students who may not be a good match. I presently have 10-15 students per week; I would not have had a connection to these students outside of WyzAnt.
Having worked through WyzAnt for just a little over two years and having accumulated 600+ tutoring hours, I can attest to the fact that the system works. I turn down students weekly because of my limited availability. I could have twice as many students if I had more time.
I set the fees to be charged. Though WyzAnt does keep a percentage of the fees, that is to be expected, as their internet company is what connected me with my students. Payments are all made to WyzAnt, who in turn pays me. I never have to ask students or their families for money! I make 3 times what I would be earning at a tutoring center.
